When making a custom diagram using building IDs on the link, there's a problem: putting more than 25 buildings on a single link (and thus making it span more than one page) corrupts the order of the buildings on the diagram.

The problem can be solved using tags. Each of the tallest buildings needs to be tagged as "State Tallest" for example. Then, a search for "State Tallest" will bring up a list of all buildings tagged that way...
